s Glalms. (on. ste -1s) This invention relates to an. improvement inpaper packages or cartons, suitable for packing fruit. vegetables andthe like for shipment and sale, and especially adapted to display thecontents of the carton when offered for sale.

In my prior U. S. Patent No. 1,741,369, granted December 31, 1929, it ispointed out that in packages of the character recited above, it isextremely desirable and advantageous to confine the contents of thepackage under moderate pressure sumcient to cause the cover to bulgemore or less, thereby not only firmly securing and preventing injury tothe fruit or other commodity thus packaged, but insuring that thecartonwill present a fully and tightly packed appearance when offeredfor sale, in spite of such shrinkage of the total ful merchandisingdemands a package having a well-filled, bulged appearance.

This obiectis attained in my aforesaid patent by providing a cover ofsuch design as to provide a mutllatabie display panel adapted to beraised above the outer edges of the cover.

My present invention contemplates and has for an object the provision ofan improved carton of the character indicated, capable of being formedfrom a single continuous sheet ofpaper, and a blank therefor.

A further object of my invention is to provide a carton and blanktherefor oi the character indicated, having provision for filling thesame from the bottom as well as for'adiusting the interior volume of thecarton in a simple and efficacious manner, for ventilating the contentsof the carton, for holding the contents securely in-place, and forfacilitating face packing. of the carton with fruit of different'sizesand in different quan-' tities.

A still further object of my invention is to provide a carton and blanktherefor of the character forth and understood, I now describe, withreerence to the accompanying drawing, a preferred form and manner inwhich my invention may be embodied and utilized. In the drawing,

Fig. 1 is a plan view of a pre-iormed sheet of paper or blank adapted tobe folded to form a carton of the character indicated hereinabove;

Figs. 2 and 3 are bottom elevational and sectional views, respectively,of a carton formed from for the purpose of raising the display paneliii.

Figs. 5 and 6 are plan and sectional views, re- 5 spectively, of acarton formed from the blank illustrated in Fig. 1, Fig. 6 being takenalong the lineVI-VI of Fig.5 and illustrating-a modified manner offoldingthe blank of Fig. 1 to provide a closure for the carton; and 10Fig. 7 is a perspective view of a portion of the carton as illustratedin Fig. 6.

Similar reference numerals designate similar parts in the several viewsof the drawing.

As will be apparent from the drawing, my carv r, ton is formed from asingle continuous sheet of paper of suitable character, having a coverpanel A, side panels B, C, D and D, insert flaps E, E,

F and F, and a bottom panel G. I

The cover panel A isdeflned by score lines i, 2, 3 and i, forming arectangle, the corresponding. sides of which also form sides of the sidepanels B, C, D and D, respectively. 'Inwardly oi the score lines i, 2, 3and t, the cover panel A is provided with perforations or cuts 5, 8, iand B which, together with a score line or cut 9, define a mutilatabiedisplay panel ill surrounded by a border or marginal section II, thelatter preferably cut away as at it to permit the insertion of a fingerThe principal corners of the display panel iii are Joined to thecorresponding outercorners of the panel A by diagonal score lines it.

' For the purpose of protecting and retaining the contents of the cartonwhen the display panel I0 is thus raised, I provide a sheet it ofCellophane" or other transparent or translucent material, of a size andshape intermediate those of the display panel ill and the entire coverpanel A. This window" sheet i6 is attached to 40 that surface of thecover panel Adestined to become an interior surface of the carton,preferably by means of a substantially continuous strip it of adhesivematerial whichsurrounds the display panel l0. The side panel B adjoiningthe cover panel A along the score line' i, terminates at score lines Ifand I8 marking the iunctures of the panel B with the side insert flaps Eand E, respectively. Similarly, the side panel C terminates at scorelines is and 20 marking the iunctures of the panel C with the sideinsert flaps F and F, respcctiveiy.

Preferably, the side panels D and D are scpa-' rated from the flaps EandF, and from E and F, respectively, by tapered cuts 22. and the scorelines i1 and 18, as well. as it and Ziiyare somewhat convcrgent, therebyproviding for a carton of tapered form, as willbe apparent from inspecwtion of the several figures and the descriptive matter hereinbelow.

The bottom panel G adjoins the side panel C along a score line 25,parallel to the score line 2, and while of generally rectangular shape,is preferably provided withdiagonal corner cuts 26, for a purpose to berecited hereinbelow.

. A score line 21 is provided, parallel to and relatively closely spacedfrom the score line 25. Parallel score lines 28 and 29 are also providednear the opposite side of the panel G. One or more, preferably two,cut-out portions 3| are provided in the panel G, one side of each ofwhich portions 3| coincides with or forms an extension of the score line28, while the ends of the cutout portion or portions 3| are connected tothe score line 29 by cuts 32, preferably although not necessarily,located at right angles to the score lines 28 and 29, thereby. forming afiap or flaps 33. Preferably, the score line 29 does not extend acrossthe flaps 33, but merely connects the sides of the flaps 33 to the sidesof the box and to each other, as shown, so that the flaps 33 are notseparated by any score line from that portion of the panel G lyingbeyond the score line 29.

When my' carton is to be formed and filled, the insert flaps E, E, F andF are first bent at substantially right angles to the corresponding sidepanels B and C along the score lines l7, |8, l9 and 20, respectively,and the side panels B and C are then bent along the score lines and 2,respectively, to substantially right angles with re spect to the coverpanel A until the upper edges of the insert panels E, E, F and Fcoincide with the score lines 3 and 4. The side panels D and D are thenbent along the score lines 3 and 4 respectively, until they meet theinsert panels E, F, E and F, and the'panels: D and D are then fastenedby means of staples 40 or other suitable fastening means to the adjacentinsert flaps E, F, E and F, respectively. The carton is thus formed andready to be filled.

I have found that the mere act of forming and securing the carton, ashereinabove described, tends to cause the cover panel A to bulgeupwardly to some extent, slight bends being made along the score linesl2, thus raising the display panels l above the outer edges of the coverpanel A. This bulge is further accentuated, however, when the carton ispacked.

In the event that the fruit or other commodities placed within thecarton are of sufficient bulk to well fill the carton, the bottom panelG is bent along thescore line 23, the portion of the panel G lyingbeyond the score line 28 being turned inwardly and placed inwardly ofand adjacent to the side panel B, to which it is then fastened by meansof staples H or other suitable fastening device. The cut-out portions 3|provide for insertion of a portion of the stapling instrument.

The bottom panel G is so positioned with respect to the remainingportions of the carton that it acts through the medium of the contentsof the carton to create or accentuate the bulge in the cover panel,thereby raising the display panel I0 above the outer edges of the coverpanel A and giving the carton a well filled appearance. This position isillustrated in Figs. 6 and 7.

In the event, however, the fruit is small or the bulk thereof does notwell fill the carton, the bottom panel G is bent sharply along the scoreline 28 to turn the flaps 33 inwardly of the carton as shown in Figs. 3and 4. In this instance sufficient bending is permitted at the scorelines 21 and 23 to provide for this difference from the position shownin Figs. 6 and '7 and to permit raising or lowering the principalportion of the bottom panel G to such a position as to cause thecontents of the carton to be firmly pressed upwardly 5 against the coverpanel A.

In this position that portion of the bottom panel G lying beyond thescore lines 29 acts as an additional support together with the flaps 33,forming extensions thereof, to maintain the bottom panel 9 in the desied position. Staples 4| are used as before, exce t that in this instancethese are preferably located in the flaps 33.

It will be noted that with the bottom panel G thus closed and fastenedto the' side panel B as at 4|, the beveled corners 26 provideventilating spaces 42 in the lower corners of the carton which permitcirculation of-air and maintain the fruit or other contents in a freshcondition. It will further be observed in Figs. 3 and- 6 that the shapeof the cut-out portions 22 provides small ventilating spaces 43 locatedin the upper-and outer corners of the carton which, while small, arenevertheless adapted to cooperate with the ventilating spaces 42 topermit circulation of air 25, through the contents of the carton.

My carton and the blank from which it is formed are preferablymanufactured from paper or fibre of sufiicient strength and rigidity toprevent injury to the contents thereof under the ordinary conditions ofshipment and storage, but I prefer to employ what is generally known asdouble-faced corrugated kraft board.

When the filled, carton is placed ondisplay and offered for sale thedisplay panel ID is readily raised by inserting a finger through theopening l2 between the display panel I0 and the Cellophane window sheetl5 and bending the display panel Ill upwardly along the score line 9. Inthis manner a prospective purchaser is afforded a good view of thecontents of the carton without permitting the latter to become soiled orotherwise damaged.

The display panel l0 may be completely .detached, if so desired, thisbeing facilitated by 45 making the score line 9 of such character as topermit detachment of the panel l0 along the score line Ill as well asalong the score lines 5, 6,

If desired, the bottom panel'G may also be provided with a ,mutilatabledisplay panel similar to the panel l0, and the same is true of the othersides of the carton, more particularly the panels B and C. Each of saiddisplay panels is' preferably provided with a window pane of "Cel- 5.

lophane or other transparent material.

In the event that several of the sides of th carton are thus providedwith mutilatable display panels, I may provide a single panel ofCellophane" and the like, which panel may cover substantially the entireblank, thereby forming in substance, when the carton is formed and thedisplay panels removed, a Cellophane bag having a structural outercasing supporting the same but not seriously impairing the view of thecontents.

While, for packaging fresh fruit and vegetables. I prefer to so form theblank and carton that the latter will be tapered, as shown in thedrawing, for many other purposes, a tapered form is unnecessary, and thecarton may then be made rectangular in shape.

It will therefore be obvious to those skilled in the art that myinvention is susceptible of considerable modification in detafl withoutde- 7 parting from the essential teaching'thereoi and is therefore notlimited to the details of the preferred example given hereinabove by wayof exemplification and illustration, but may variously be embodiedwithin the scope of the claims hereinafter made.
